Your brain contains about 100 billion microscopic cells called neurons-so many it would take you over 3,000 years to count them all. Your brain generates enough electricity to power a lightbulb.

No computer can come close to your brain's awesome ability to download, process, and react to the flood of information coming from your eyes, ears, and other sensory organs. Accessing the signals coming from your eyes, your brain quickly calculates when, where, and at what speed you will need to dive to intercept her. It is a structure so amazing that a famous scientist once called it "the most complex thing we have yet discovered in our universe." Your brain is faster and more powerful than a supercomputer. From enabling you to think, learn, create, and feel emotions to controlling every blink, breath, and heartbeat-this fantastic control center is your brain. You carry around a three-pound mass of wrinkly material in your head that controls every single thing you will ever do.
